Type Mapping Strategy

Research into converting duckling's Rust types to Ruby values via Magnus.

Note (PR #3 review): This subtree's recommendation (manual Magnus hash mapping, Option B in serialization-options.md) is what shipped for 0.2.0, but it's anchored in matching pyduckling's Hash-based decisions. A reviewer flagged a preferred future direction away from Hash primacy — symbol-keyed serde_magnus output consumed by Ruby pattern-matching factories that build Data value objects instead. Tracked as issue #32 (API shape) and issue #33 (naive-time/timezone handling, ActiveSupport-style, for v0.3.0). See "Option D" in Serialization Options: Rust to Ruby for the write-up.

Documents

File	Description
Serialization Options: Rust to Ruby	Compares the three conversion approaches (serde_magnus, manual Magnus mapping, JSON round-trip) with verified serde attribute analysis and a recommendation.
Target Ruby Hash Schema (0.2.0 — Time Entities Only)	Defines the target Ruby Hash shape for time entities in the 0.2.0 release, documenting the pyduckling compatibility target and the open NaiveDateTime timezone question.
Magnus Type Conversions	Documents Magnus 0.9.0's built-in Rust-to-Ruby type conversions, the chrono feature gate, and example Rust code for manually building the time entity hash.
